New Jersey Gov. Chris Christie used his blunt, East Coast style this morning when he urged Iowans to go to Tuesday’s caucus for Mitt Romney and to help defeat President Obama next fall.

“The president is going to try to convince you somehow that he deserves to be rehired. Well let’s be real clear, real clear. President Barack Obama came out to Iowa three years ago, and he talked to you about hope and change. Well let me tell ya, after three years of Obama, we’re hopeless and changeless, and we need Mitt Romney to bring us back, to bring America back,” said Christie, who many Republicans hoped would run for president but who decided to endorse Romney instead.

He drew laughter with a mock threat: “New Jersey’s watching you too. We’re watching you real closely. And I want to tell you something. I want to tell you something really clearly. I’m in a good mood this morning. I’m feeling happy and upbeat. I’m happy to be with Mitt and Ann. But let me tell ya, if you people disappoint me Tuesday, if you don’t do what you’re supposed to do on Tuesday for Mitt Romney. I will back, Jersey-style. I will be back.”
